From: Martin Pitt <martin.pitt@xxxxxxxxxx> Date: Wed, 11 Feb 2015 15:26:52 +0100 Subject: rules: Fix by-path of mmc RPMB partitions and don't blkid them Linux 3.10+ exposes RPMB (Replay Protected Memory Block) partitions of MMC devices [1] ; trying to read them with blkid or other unspecific means will cause kernel buffer I/O errors and timeouts. Blacklist those to prevent creating wrong by-path links and blkid'ing those.
